91 use the mode of OP0 to count the number of significant bits.
92 (extract_bit_field_1): Remove unit, offset, bitpos and
93 byte_offset from the outermost scope. Express conditions in terms
94 of bitnum rather than offset, bitpos and byte_offset. Move the
95 computation of MODE1 to the block that needs it. Use MODE unless
96 the TMODE-based mode_for_size calculation succeeds. Split the
97 plain move cases into two, one for memory accesses and one for
98 register accesses. Generalize the memory case, freeing it from
99 the old register-based endian checks. Move the INT_MODE calculation
100 above the code that needs it. Use simplify_gen_subreg to handle
101 multiword OP0s. If the field still spans several words, pass it
102 directly to extract_split_bit_field. Assume after that point
103 that both targets and register sources fit within a word.
104 Replace x-prefixed variables with non-prefixed forms.
105 Compute the bitpos for ext(z)v register operands directly in the
106 chosen unit size, rather than going through an intermediate
107 BITS_PER_WORD unit size. Simplify the containment check
108 used when forcing OP0 into a register. Update the call to

130 directly to store_split_bit_field. Assume after that point that
